Nested Grid

[otaviors]

Hi!

How do I create a nested grid using GXT. Is it possible to add another grid or a HTML table to the content of a Row expander plugin? If this is not possible, is there another way to implement a nested grid?

Thanks!

TreeTable?

Is it possible to configure multiple headers on a TreeTable? For example, could I use it to show a master detail relationship below where the user clicks on the "+" button to access the details?

you would need to write your own grid plugin - see > http://extjs.com/explorer/#gridplugins and > http://extjs.com/explorer/#livegroupsummary for examples (combine parts of LiveGroupSummary and Expanding Row)

Thanks for the info Grant, but I'm new to GWT and I couldn't find any documentation on how to build my own plugin. It looks like i need to extend the


protected String getBodyContent(ModelData model, int rowIndex)

method of the RowExpander class in order to get my nested grid rendered.

Is there any kind of documentation or example on developing customized plugins?

Thanks again!

I would be interested in this as well. Basically, i need to do the same thing you are (general/detailed relationship when a row is expanded)

I am also looking for similar behavior with grid , any clue how to do this ?

You can use the Grouping Grid http://www.extjs.com/examples/pages/grid/grouping.html

I ended up using this heavily modified for my use case. If you have a lot of data being displayed and are using paging, you will have to override a few GXT classes to get everything to work.

Thank you very much for your reply . But I am trying to create grid something like
http://www.openfaces.org/demo/treetable/TreeTable_basicFeatures.jsf .
Each row when expands render another grid (I am not insisting that it should be another grid ) . But I need to take child nodes and need to render as child grid .

[dpope22]

Have you looked at the TreeGrid sample?

http://www.extjs.com/examples/pages/treegrid/basic.html

The grid in your example is similar to GXT's TreeGrid.

Yea I did , but problem with Treegrid is Folder nodes doesn't allow attributes in it's row :) . In otherway, I don't want "Folder" all rows should look alike except expander for grouping
